Translucent dragon cups, some more

            Here are some more pictures of the translucent dragon cups. I threw them on the wheel and trimmed them, then brushed black slip on around the outside. After letting the slip stiffen, I carved out the dragons. The reason they are so translucent is that they are made of porcelain. Not all porcelain and porcelain-like clays have this property, so when I chose my clays back in the fall I specifically selected one that was recommended for its translucence.
            Having never worked with translucent porcelain before, I'm amazed with the stuff. I love working with porcelainous clays, I knew that before. But after hearing all about how difficult it is to make translucent pots, I guess I never expected it to work this well. It really worked!




            I knew as soon as I took these out of the kiln that they were even better than I had hoped. The first thing I usually do when I pull something out of the kiln is to scoot into the sunshine to get a good look at it. These cups are translucent enough that you can see the effect in normal light. You can see it as a little creamy glow around the foot in these pictures:




             I'm pleased with nearly all the pots in this firing, but these are the best. The translucence is something I can only guess at when I'm making them, so I paid a lot of attention to the other aspects. I used my tiny rubber rib to make them smooth, and worked hard on the carvings to make them clean and crisp. I also sanded them gently after both firings, so the bottoms feel good in the hand. I love my abstract dragon design; it looks good in two colors like this and I can reliably make the dragons look related to each other. I also love making them, especially the carving part. I do get tired of doing the same thing after six cups, but that's what bowls and plates (and Kickstarter rewards...) are for.
            And fussy though my camera seems to be about bright sunlight, I have to give it credit for doing a good job in the dark. All I did was click the button and hold very, very still. (It helps to rest my hands on something sturdy. A tripod would work, too.) And when I hold still enough, I get pictures like these: 



            That's what they actually look like with candles in them. It's beautiful. I also found that the sides of the cup remained cool despite the hot candle inside, so I could pick them up and move them around without worrying about hot fingers. I think at this point I have to 1. make more of these cups; and 2. make some "cups" with shades/lids specifically for the purpose of holding candles. Because, wow. Ceramics = the real magic we have in the world. I can make mud that glows.

Translucent dragon cups

            I just took some photos of a set of dragon cups from this firing. I took the pictures at night so that I could try putting tea candles in the cups to photograph the translucence... and it worked very well! I'll put up some more pictures in the morning, but I couldn't wait to post this.
            The cups in normal light:


             The cups with candles inside them as the only light source:



            I think I'm a little less depressed now.

Glaze adventures!

            I recently mentioned my glazing experiments in the latest firing. Now I have some more pictures to share! I already showed the octopus cup and the blue and white dragon plates. This post is about the rest of the group of cups that the octopus cup is related to.
            These cups aren't really a set - they are all different shapes, all have different designs, and don't really "go together." But they are all the same size, made of the same red stoneware, and glazed using only two glazes (Mottled Spice and Deep Firebrick).
            The octopus cup is different from the others in that I left most of the cup unglazed, and painted the octopus design directly on the bare clay. That looks like this:


            The red octopus is shiny, while the clay is rough and matte, so the edges of the design are sharp and clear. On the other cups, I glazed the outside of each cup and brushed the design on top of that background glaze. This resulted in more smudgy, less defined edges. Like this tree:


            Since both the background and the tree design are shiny, the tree doesn't stand out as much as the octopus on the previous cup. Another difference is that the brown glaze of the tree melted flat into the red glaze, so the tree isn't raised - you won't feel a bump under your fingers when you hold the cup. It's more like a drawing on a piece of paper.
            The Mottled Spice (brown) doesn't contrast in color as much as I expected from the red. The tree is actually much subtler than I thought it would be. It was difficult to photograph because of this, but I like how the cup looks. It encourages you to really look at the cup as you are holding it, because the tree doesn't pop out at you. I'm all for people taking a closer look!
            I used this glaze combination for a dragon cup, as well. The effect is similar:


            I'm calling this a shadow dragon. You can see the design, but it's understated. You see the dragon as you turn the cup, but never all of the dragon at once.  Again, this is difficult to capture in photos, but I found that in the sunshine there was enough light to allow the dragon to show. Although the dragon is visible in indoor light, I wasn't very good at capturing it in a picture.
            Then I have cups with the opposite glazing: red against brown. This cup has mushrooms on it:



            As you can see, the red glaze slid down a bit as it melted. The lines of the design are thus less sharp, particularly on the undersides of the mushroom caps. This makes a neat-o looking texture on the mushrooms. I think they look like lava mushrooms. I don't think this combination would work well with an octopus, because it would muddy up the tentacles, but I think it's just fine for these mushrooms. They don't have such fine details.
            I also used this combination for a design that included finer details:


            Am I upset that some of those details vanished in a wash of red? Nope. I was hoping that the red would help this bird look like a phoenix. The selective loss of detail doesn't strike me as out of place because of the coloring - it's a flaming phoenix, so parts of the bird are obscured by fire. I am pleased, however, that the upper wing retained the feathers that I carefully brushed there.
            Overall I'm happy with these cups. Sometimes glaze experiments go well, and sometimes they don't. Often they don't quite look how one imagined they would! I am glad I was able to make hypotheses about how these glazes would act that came out so well. I think the earthy colors are handsome and warm. I like these glazes with red clay. I ended up with five great cups. I count this glaze experiment as a success!

Unicorn vase

            This is a tiny vase with a flaming unicorn. I carved the unicorn, then used orange and red washes for the color, then a clear glaze on top.




            This vase is really quite small: 3.25 inches tall. Just the right size for several grape hyacinths!


             The grape hyacinths are from the garden here. They are blooming along with the daffodils currently. I'm doing a lot of work in the garden this spring, and it's great to be able to take pictures of my work outside again. 
            I leave you with a close up of the unicorn:

Blue and white dragons

            Another glaze adventure: blue and white dragon plates. These are porcelain plates that I painted dragons on with blue glaze, then poured an even layer of clear glaze over the dragons. I'm using a Mason stain for my blue, so it's not the deep color of pure cobalt, but a softer, brighter blue.



           The plate above is my favorite of the two. The dragon is more complex, and curled in a way that fills up the space on the plate with its presence. I also like its face and wing a lot.



            On the other hand, the dragon on the second plate has a pretty cute face, and I like the frill and wing on this one, too. This dragon is a little simpler and a little coarser.
            Another difference between these two plates is the way I glazed the underside of each. On the first plate, I allowed the clear glaze to spill over when I was glazing the top of the plate and left the drips rather than removing them. On the second plate, I painstakingly removed all the dripped glaze (except for one tiny bit I missed. White glaze on white pot - hard to see!). The clear glaze is glossy, but the bare porcelain is matte. So the drips are a bit subtle on the first plate, appearing mostly through the way they reflect light.


            The second plate looks like this:


            Bare porcelain is still very white without glaze, and I gently sanded the unglazed areas with fine sandpaper after the plates came out of the kiln. Sanded porcelain feels very nice under the fingers, and I usually do this to the foot of every pot I make. It makes the pot feel more refined. I think often about how pots will feel when touched as I am making them. Where will it be rough? Smooth? Slick? Grippy? Glossy glaze feels different than matte glaze, and porcelain feels different than stoneware.
            I often use the roughness of my red stoneware on purpose as a contrasting sensation to shiny glazes. I often smooth porcelain as much as I can in the raw state, then sand it after bisque firing and after glaze firing. The last sanding of the porcelain usually doesn't require much time at all. I also do my best to make the bottoms of pots and sculptures tabletop friendly. I once gave someone a handsome vase I had made, and she set it on a wooden table. This was just fine until someone decided to turn it around to look at the other side without lifting it from the table, and the rough clay left scratch marks. Yikes! Since then I think about the bottoms a lot more. Every pot gets set down somewhere, and it needn't leave damage behind.

Flowerpots and an octopus

            I unloaded the kiln this morning. As always, I'm too excited to pull out the pots to get pictures of the whole kiln full of work. But I've been taking pictures of individual pots, so I do have something to share!
            A flower pot with two sea monsters chasing each other around the rim:


            A flower pot with walnut texture around the rim:


            The two flowerpots above are 8 inches wide and about 6.5 inches tall. I enjoyed making them. The clay is very rough, and that seems to fit well with flowerpots.
            I mentioned yesterday some of my glaze experiments with this firing. A particularly successful experiment is this octopus cup:


 

            I'm very happy with that octopus. The thing that makes the octopus work so well is that I painted him/her directly on the bare clay, rather than over another glaze. So the edges are sharp and clean, which I think is good for the tentacles. If the tentacles were smudgy, it wouldn't look as good. 
            My light box setup leaves something to be desired, I think. It's hard to get the colors right, and that bothers me a lot. I don't like my white background, but I'm having some success with a pale blue background and a black background. Also my camera is old, and often doesn't respond correctly to lighting conditions. Perhaps when I sell enough pots, I'll get a new camera.

Vases!

            Here are a couple of vases that came out of the kiln last week. This one has a jellyfish:


            And waves on the back:


            This jellyfish vase is porcelain. I brushed green slip over it, then carved the waves and jellyfish through the slip so that they appear white. Then when the vase was bisque fired, I brushed blue stain on the waves and partially sponged it off. This vase will be available in my Etsy shop this week!
            And this vase has cuttlefish! (This one has already been claimed; it will not be in my Etsy shop.)




            These vases are both glazed with a new glaze I mixed for this firing. It's the zinc-free clear with 4% Delphinium blue Mason stain added. I chose this blue because it is bright, and tilted just a bit toward purple. At this percentage, it makes a typical saturated blue. I'm planning to try it at 2% or less to see if I can make it more pale. I'm also considering mixing this blue stain with a green stain to see what happens. I like blue, but I tend to favor less intense shades (I'm a fan of celadon blues/greens, for instance).

Serving dishes

            Here are some serving dishes that came out of the kiln on Wednesday! I am very pleased with all of these. The first two will be available in my Etsy shop in a few days. The last one is already spoken for.
            First up is a shallow serving dish in red and white with dragons and swirls:




            I was a little worried that the red glaze would leave droplets on the white glaze, since in the last firing it kinda spattered all over the place. Not this time, though - perhaps the changes I made to the firing schedule magically solved the problem? In any case, I'm pleased that the white areas remained white. I noticed that where I accidentally brushed a bit of the red over the white on the rim, it made a lovely pale blush color. I may use this on other pots in the future intentionally for subtle effects.


            And this bowl has three dragons on it. I took close ups of all three. I like them very much! I think I may work with this red and white theme some more in the future. It seems like a good color combination for dragons and phoenixes. Maybe other magical critters, too... any ideas?




            This next piece is red stoneware with clear glaze just on the food surface.



            The clear glaze looks cloudy here because it has teensy bubbles in it. The bubbles interfere with the light passing through to the clay surface under the glaze. Over red stoneware, this makes the glaze look white. Over porcelain (like the previous serving dish), it adds some depth to the surface, but since the porcelain is white and the glaze is clear/white, it doesn't appear to change the color.




            This red stoneware is the Hawaiian Red I mentioned in this post. It's very much a rusty orange, and I do like the color. The things I don't like about this clay are that it feels like sandpaper to throw, and it comes from far away - this box of clay took a month on special order to arrive at my semi-local pottery supply. Although it is half the price of the porcelain I use!
            I think when I am close to the end of this box of red clay I will try a different, more local clay. I'd rather use clay that is nearer me anyway so that it doesn't have to use up gas all the way across the country to get here.
            And here is the last serving bowl for this post. As mentioned above, this bowl has been claimed already. The two above, however, will be available on Etsy. So if you like them, keep an eye out on my Etsy shop!



            This bowls is glazed only on the inside. The texture on the outside was created when I trimmed the bowl; the grog in the clay gets dragged across the surface by the trimming tool as I work. I like the effect in this case, but I'd rather have clay with less grog - it's abrasive to my hands, and wears down my tools quickly.


             I'm very happy with the glazing on this bowl! The dark brown glaze is actually the Mottled Spice from this post. What happened? It's much thinner here, and where this glaze is thin, it's this dark brown that reminds me of coffee beans or dark chocolate. Also when it's thin it doesn't run off the pot and get cemented to my kiln shelves!
            I've now tested the two extremes of this glaze - super thin and super thick - and there's a good bit of wiggle room in between. As I continue to use it I'll get a better idea of how it will look at different thickness of application. I think this glaze is very nice. I like it when it's this coffee bean color, and I like the appearance of texture it creates when it's thicker. It allows me to have one glaze that can be used many different ways. This is good, because I don't really want to keep too many glazes in my studio, but I do want to have a lot of variety of surface on my pots and sculptures. 
            Here is a close up of the inside. You can tell the glaze is thin because you can see the texture of the pot through it.
